Larger space is occupied in terms of degree still.In the age of this cell phone components layout an inch of land is an inch of gold, the slimming of whole camera lens module is
Inexorable trend.
In the periscopic Zoom optic lens module of existing mobile phone, total reflection prism is all-trans using the glass of glass material
Prism is penetrated, because glass material is relatively soft being easily scratched, strengthens glass need to be set in front of glass total reflection prism
The protecgulum or lens of material is protected.
The Chinese patent of Application No. 201320173535.X discloses a kind of mobile phone with periscope type lens, including machine
Shell and the periscopic mobile lens module in casing；The periscopic mobile lens module includes adjacent front successively
Microscope group, flexion formula component, rear lens group and photo-sensitive cell, the flexion formula component are located at the incident incidence of front lens group described in Jing
In the light path of light and the flexion incident ray, the light path of the incident ray after flexion is provided with the rear lens group, it is described after
The primary optical axis of lens group is overlapped with the centrage of photo-sensitive cell；The key light of the primary optical axis of the front lens group and the rear lens group
The angle of axle is less than 180 degree.The mobile phone with periscope type lens of the utility model, relieves the camera lens light of the photographic head of mobile phone
The restriction that overall length is limited to mobile phone thickness is learned, the camera lens of the photographic head of mobile phone can be expanded using larger sized photo-sensitive cell
Total pixel, takes pictures and will not produce noise, can design the camera lens of more high image quality, improves the shooting quality of the photographic head of mobile phone.
But contain front lens group in above-mentioned periscopic mobile lens module, for protecting to flexion formula component, increase
The big thickness of whole camera lens module.
Utility model content
In order to solve above-mentioned technical problem, this utility model provides a kind of mobile phone uncovered periscopic Zoom optic lens
Module.This utility model adopts sapphire total reflection prism, and eliminates the protecgulum or lens being arranged in front of prism originally,
So as to further reduce the thickness of periscopic Zoom optic lens module, thinner smart mobile phone is can configure.
Concrete technical scheme of the present utility model is：A kind of mobile phone uncovered periscopic Zoom optic lens module, including
Sapphire total reflection prism, lens group and photosensitive sensor；The sapphire total reflection prism is located in the light path of incident ray
And 90 degree of reflection incident raies, the lens group and the photosensitive biography are sequentially provided with the light path of the incident ray after reflection
Sensor, the primary optical axis of the lens group are overlapped with the centrage of photosensitive sensor.
Total reflection prism of this utility model using sapphire material, because sapphire quality is harder, wearability is good, is difficult to draw
Wound；Therefore, it is possible to cancel the setting of protecgulum or frontal lens, the thickness of periscopic Zoom optic lens module is further reduced, is made
Its configurable thinner smart mobile phone.And due to reducing an optical element, additionally it is possible to reduces cost.
Preferably, the sapphire total reflection prism is prism.
Preferably, also including the filter element in the light path of incident ray.Filter element can be filtered off need not
Infrared light, improve image quality.
Alternatively, the filter element is the optical filter that can reflect infrared light, and the optical filter is positioned at the camera lens
Between group and photosensitive sensor in the light path of incident ray, and the centrage of optical filter is overlapped with the centrage of photosensitive sensor.
As further, preferably, described filter element is the filter coating for being transmissive to infrared light, the filter coating plating
On the reflecting surface of the sapphire total reflection prism.
When using above-mentioned optical filter, the colour cast that infrared light in secondary reflection again to lens group, can be caused to be imaged
And ghost image.And when adopting above-mentioned filter coating, film layer can allow infrared light directly through preventing the infrared light being not needed to enter
Enter lens group.So not having secondary reflection.Simultaneously because reducing rearmounted optical filter, can further reduce camera lens mould
The thickness of group.
It is compared with the prior art, the beneficial effects of the utility model are：This utility model adopts sapphire total reflection prism,
And the protecgulum or lens being arranged in front of prism originally is eliminated, so as to further reduce periscopic Zoom optic lens module
Thickness, can configure thinner smart mobile phone.And due to reducing an optical element, additionally it is possible to reduces cost.
